Portable Cellphone + Wifi Jammer J-240A-Pro
I had a smaller version [.2W] of a signal blocker before. The J-240A-Pro is exactly what it is a 'Professional' signal blocker at 3W output, I find it to be the best. Robust and delivers faster and further. The customer service from the jammer4u team is of the highest quality. To my door in less than 10 days. I highly recommend this item from this site. You will not be disappointed. George [UK].
